Woodside Petroleum Ltd. has let a contract to DOF Subsea Australia for decommissioning work on depleted Enfield oil field in the Northwest Shelf license WA-28-L offshore Western Australia.
The project will involve recovery of 18 subsea Christmas trees, 18 flow bases and associated spool sections, one wellhead severance, and the recovery of up to 18 temporary guide bases from the seabed, DOF said.
The contract includes project management, engineering, fabrication, and decommissioning services. Work is scheduled for the third and fourth quarters of this year using the Skandi Hercules vessel, DOF said.
Enfield was originally brought on stream in 2006 via the Nganhurra floating production, storage, and offloading vessel (OGJ Online, Sept. 19, 2007). The field was shut in at the end of its production life in late 2018 (OGJ Online, Aug. 15, 2017).
Woodside is operator with 60%. Mitsui E&P holds 40%.
